InvalidCastException when generating source (since 2.0.3)

[jhartmann123]

When I updated to 2.1.0 the following message started to appear when compiling:

Warning	CS8785
    Generator 'ProjectionExpressionGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. 
    Exception was of type 'InvalidCastException' with message 'Unable to cast object of type 'Microsoft.CodeAnalysis.CSharp.Syntax.MemberAccessExpressionSyntax' to type 'Microsoft.CodeAnalysis.CSharp.Syntax.SimpleNameSyntax'.'

Attached is a repro. It still works with 2.0.2. Starting with 2.0.3 this message appears.

Note: I always had to rebuild twice when switching versions in order to have the warning vanish/reappear.

Thanks for brining this up and thanks for the repro!

This indeed is a regression since 2.0.2 and it affects named types (Enums, static classes, ....). A fix will be merged shortly
